.....ok so you really did manage to convince a restaurant to make this dessert?
Thanks for asking.

I had to RUN OUT for some of the ingredients.

Which was tough, because it was about 11 PM and just about every place was closed.
I knew that the restaurant we were in had ice cream and chocolate fudge. And I knew that the really tough part was going to be the raisins. I got up from the table and took the waitperson aside, and asked if they had raisins. Came the dreaded answer: no.

I went back to the table and excused myself, as casually as possible. There was a yogurt place next door which was still open for a few more minutes, so I bolted to there. They had strawberries, but no raisins there either.
Across the street there was a gas station with one of those mini-marts. I
knew that a mini-mart would have those little boxes of raisins.
But the gas station was closed.

So now I'm sprinting all over the street, at 11 PM, looking for raisins .....Christopher Shih and his wife (not to mention my wife) sitting in the restaurant and maybe wondering what the heil I was doing, but hopefully not thinking about it too much.
I saw across this big intersection and halfway down the next block, there was a supermarket -- and it seemed to be open!
Paydirt.

So now I turn up the sprint to full gear, doing like 100 yards in 9.3 seconds

.....and I buy my raisins. Also some little candles -- I was lucky that they had black-and-white striped ones that made them look sort of like piano keyboards.
So now I sprint back down the block and across the intersection, trying a little bit not to get run over by a few trucks, I go back into the yogurt store for the strawberries, then walk back into the restaurant, as calmly as possible under the circumstances, and get the dish of ice cream with chocolate fudge from the waitress, and start arranging the other stuff on it. My wife still has no idea what I'm doing. When I've got it all put together, I step over to Chris and his wife (they were right next to my wife), I motion for a little silence

and I make the presentation.
They sort of got it.

Best part of it was, Chris immediately started eating it.
